The Claim

In dairy cows, vitamin B6 levels in the rumen increase during nighttime and are associated with upregulated expression of the MCT1 protein in the rumen epithelium, which may enhance the transport of acetic acid from the rumen into the bloodstream.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works

In plain English

In dairy cows, vitamin B6 goes up in the stomach at night, and this might help move more acetic acid into the blood by turning on a protein called MCT1.

Vitamin B6 levels in the rumen are elevated at night and are associated with increased expression of the MCT1 protein in the rumen epithelium, which may enhance the transport of acetic acid into the bloodstream in dairy cows.

What the research says

1 study

  1. Study: Circadian Rhythm Enhances mTORC1/AMPK Pathway-Mediated Milk Fat Synthesis in Dairy Cows via the Microbial Metabolite Acetic Acid.

    The study found that at night, dairy cows have more Vitamin B6 in their stomachs, which helps move more acetic acid into the blood—just like the claim says.
